I did an upgrade to the 2.6.4 kernel and changed from devfsd to udev. About a week or so after that upgrade my airport card mysteriously quit working. I reloaded modules rebooted, cleared nvram, tried a bootcd but no luck. It Appears that the hardware is broken. Frustrated I left my laptop plugged in and sitting for about a day, but when I returned and tried again...It was working! So... I take the pb to work work all day, close it at 4pm, go home open it and again the card is dead. At this point I run the apple hardware test cd which claims no problems, I re-seat the airport, I rebuild a kernel: Still no luck. I wipe the laptop install dualboot OSX and linux: the card works for a day then again I close the book go to work open it and dead airport. OSX couldn't even utilize it. I call Apple get a replacement, replace it, bingo im back up. I use the new card from 12pm today till 6pm, closed the book to go home, I get home and poof the second card is doing the same thing. It appears that something in linux is killing or setting the airport card to an odd/off state. OSX sees no problems but the card is useless still. I've used a dlink usb wireless card so I know this is not related to the ap's and even setting up an ad-hoc network in OSX my other wireless toys will not see it. Reproducible: Always Steps to Reproduce: 1. modprobe airport 2. iwconfig essid any key off nick REdOG 3. /etc/init.d/net.eth1 start 4. close lid 5. move to an new ap's area 6. open lid. Actual Results: Airport card stops functioning under any operating system. Expected Results: Airport card should wakeup see that its ap is out of range and continue looking. I've done this to 2 airport cards. Cannot figure out how to turn them back on so if I can get them backon I would like to try to replicate this again. So far Ive only been surprised by it.
The airport card will revive its self If I remove it from the laptop for a few hours. I will try to replicate the problem a few times with diffrent kernel versions.
I think this is being set off by powering up and down the nic. But now I don't think its related to the kernel, nor the airport cards. Im closeing this bug untill I get the laptop fixed and try again.
